In a classic bit of marketing razzle dazzle, Disney claims Friday’s “Tomorrowland” began with the discovery of a mysterious box in the archives. It was marked “1952” and contained artifacts and documents relating to projects Walt Disney was working on near the time of his 1966 death, including exhibits he created for the 1964 World’s Fair.

Writer Damon Lindelof — a veteran of TV’s “Lost” and no stranger to creating mystery — says the box was a way to build Christmas Eve-like anticipation.

“Walt Disney understood that the story started before you came into the tent,” he says.

Real or not, here’s an up-close look at the box of inspiration for “Tomorrowland.”

DisneyThe 9-inch Phonovision record is dated November 1963 and contains a never-before-seen piece of animation. The footage, narrated by Orson Welles, detailed a secret society of scientists and inventors, including Nikola Tesla, Thomas Edison, Walt Disney and Jules Verne. The “Tomorrowland” script originally contained a larger subplot about this society, called Plus Ultra, but much of it was cut for time.

This issue of Amazing Stories magazine, published in August 1928, is notable not only for stories by H.G. Wells and E.E. Smith, but also for the first appearance of Buck Rogers, created by Philip Francis Nowlan. The hero, who gets flung into the future, has parallels to the film’s main character, a teen girl (Britt Robertson) who finds herself transported to the futuristic city of Tomorrowland via a magic medallion.

DisneyA collection of blueprints for the “It’s a Small World” attraction created for the 1964 World’s Fair shows a secret structure beneath the pavilion — that part’s printed in invisible ink. In the film, a boy (played by George Clooney, left, as an adult) gains access to the structure, which leads to the futuristic city of Tomorrowland.

The book “Model Research,” by Alex Roland, is a history of NASA from 1915 to 1958. Curiously, it was published in 1985. The film’s message is about the need for innovation and exploration, of which NASA is held up as an example.

The box contains several photos of Walt Disney with various people. The top photo shows the studio head with a military man. (Disney was active in the war effort during World War II.) The photo below appears to be Disney with Amelia Earhart — likely a forgery. Earhart does not appear in the film.

A piece of a jet pack from a proposed Disney ride called Jet-Man. The never-built attraction was to simulate the experience of soaring through the sky using a rocket-powered jet pack. How it relates to the film: As a boy, Clooney’s character invents a jet pack that he uses to fly around Tomorrowland when he first arrives.
